Separate protection component

ABSTRACT

The present invention discloses a separate protection component, which comprises a first covering body and a second covering body. A first covering surface of the first covering is connected to a first bottom of the first covering to form a first receiving space. The second covering body is disposed in the first receiving space. A second covering surface of the second covering body is connected to the second bottom portion of the second covering body to form a second receiving space for receiving the ankle. When the first bottom is applied with an external force and the external force is not less than a maximum static friction coefficient, the contact surface moves in a direction so that the contact area between the contact surface and the sliding surface is changed from the first contact area to a second contact area.

FIELD OF THE INVENTION

The present invention relates to a technical field of foot protection,particularly, to a separate protection component for preventing footinjuries for users.

BACKGROUND OF THE INVENTION

Conventionally, users generally protect their feet by wearing shoes inorder to avoid directly contacting the ground while walking, racewalking or running.

However, users may possibly have what is commonly known as “anklecapsize” due to inappropriate shoes (eg. size, shape) or environment(eg. pebble or gravel land, bumpy road). The severity of capsize can byhigh or low, if mild, pain may by relieved with little rest; if serious,even walking can by challenging. In some worse cases, “chronic ankleinstability” may arise.

In view of the above, the present invention provides a separateprotection component capable of overcoming the aforementionedshortcomings of the prior art.

SUMMARY OF THE INVENTION

The first objective of the present invention is to provide a separateprotection component as described above capable of protecting ankles.

The second objective of the present invention is to provide saidseparate protection component comprising a first covering body and asecond covering body, the second covering body being disposed in thefirst covering body.

The third objective of the present invention is to provide said separateprotection component, wherein a sliding surface of the second coveringbody contacts a contact surface of the first covering body, creating amaximum static friction coefficient by means of the sliding surfaceoverlapping the contact surface.

The fourth objective of the present invention is to provide saidseparate protection component, wherein when the second bottom portion isapplied by an ankle with an external force at least equal to the maximumstatic friction coefficient, the first covering body and the secondcovering body generate a combination variation to achieve capsize-freeankle protection by the second covering body.

In order to achieve the aforesaid objectives among others, the presentinvention provides a separate protection component capable of protectingan ankle. The separate protection component comprises a first coveringbody and a second covering body. The first covering body includes afirst covering surface and a first bottom portion. The first coveringsurface is connected to the first bottom portion to form a firstreceiving space. The second covering body is disposed in the firstreceiving space. The second covering body includes a second coveringsurface and a second bottom portion. The second covering surface isconnected to the second bottom portion to form a second receiving spacefor receiving the ankle, the second covering surface being connected tothe second bottom portion. Wherein, a sliding surface of the secondbottom portions contacts a contact surface of the of the first bottomportion so the sliding surface overlaps the contact surface by a firstcontact area. The sliding surface forms a maximum static frictioncoefficient relative to the contact surface. Wherein, when the firstbottom portion is applied with an external force and the external forceis not less than the maximum static friction coefficient, the contactsurface moves in a direction so that the contact area between thecontact surface and the sliding surface is changed from the firstcontact area to a second contact area.

Compared to prior art, the separate protection component disclosed inthe present invention effectively prevent an ankle from capsizingtogether with shoes when the shoes capsize which generally causes ankleinjuries.

This is done for convenience ofdescription only and providing a general meaning to the scope of thepresent invention. Therefore, unless clearly stated otherwise, thedescription should be understood to include one, at least one, and thesingular can also includes plural.

In the present invention, the terms “comprising”, “including”, “having”,“containing”, or any other similar terms are intended to encompassnon-exclusive inclusive. For example, a component, structure, article,or device that contains a plurality element is not limited to suchelements as listed herein but may include those not specifically listedbut which are typically inherent to the component, structure, article,or device. In addition, the term “or” means an inclusive “or” ratherthan an exclusive “or” unless clearly stated to the contrary.

Please refer to FIG. 1, where it is a sectional structure diagram of afirst embodiment of a separate protection component of the presentinvention. In FIG. 1, the separate protection component 10 providesprotection for an ankle (not shown). The separate protection component10 comprises a first covering body 12 and a second covering body 14. Inthis embodiment, the first covering body 12 and the second covering body14 are shoes for illustration purpose.

The first covering body 12 includes a first covering surface 122 and afirst bottom portion 124, for example, the first covering surface 122may be shoe exterior and the first bottom portion may be shoe sole. Thefirst covering surface 122 is connected to the first bottom 124 to forma first receiving space (FSP), specifically, the two ends of the firstcovering body 122 are respectively connected to the first bottom 124 toform the first receiving space FSP. In this embodiment, the firstcovering surface 122 is connected to the first bottom 124 to form afirst hole 126 for connecting the first receiving space FSP and spaceoutside the first covering body 122.

The second covering body 14 includes a second covering surface 142 and asecond bottom portion 144, for example, the second covering surface 142may be shoe exterior and the second bottom 144 may be shoe sole. Thesecond covering surface 142 is connected to the second bottom 144 toform a second receiving space (SSP) for receiving an ankle,specifically, the two ends of the second covering surface 142 arerespectively connected to the second bottom 144 to form the secondreceiving space SSP. The second covering body 14 is disposed in thefirst receiving space FSP. In this embodiment, the second coveringsurface 142 is connected to the second bottom 144 to form a second hole146 for ankle insertion into the second receiving space SSP.

When the second covering body 14 is inserted into the first coveringbody 12, a sliding surface 1442 of the second bottom 144 contacts acontact surface 1242 of the first bottom 124 so the sliding surface 1442overlaps the contact surface 1242 by a first contact area. Wherein, theaforesaid sliding surface 1442 and the contact surface 1242 are at leastone of smooth, nicked, grooved or granular shaped. Furthermore, thesliding surface 1442 and the contact surface 1242 may be entirely orpartially overlapped. The sliding surface 1442 forms a maximum staticfriction coefficient relative to the contact surface 1242, and when anexternal force F, which is equal to or smaller than the forcecorresponding to the maximum static friction coefficient, is appliedbetween the sliding surface 1442 and the contact surface 1242, no (orslight) movement occurs between the sliding surface 1442 and the contactsurface 1242; contrarily, when the external force F applied between thesliding surface 1442 and the contact surface 1242 is equal to or largerthan the force corresponding to the maximum static friction coefficient,no (or slight) movement is changed to movement (or sliding) between thesliding surface 1442 and the contact surface 1242.

For example, in general, a force F is mainly from the exterior and theinterior, wherein the exterior is primarily acted upon the firstcovering boy 12 by the surroundings. However, in spite of where theforce F is generated from, as long as the force F is equal to or greaterthan the maximum static friction coefficient, the contact surface 1242shall, for example, move towards left (or right) of the second coveringbody 14, thereby changing the contact area of the contact surface 1242and the sliding surface 1442 from a first contact area to a secondcontact area, as show in FIG. 3. Wherein the second contact area issmaller than the first contact area, for example, the second contactarea is no greater than 5 square centimeters.

Please refer to FIG. 2, where it is a sectional structure diagram of asecond embodiment of a separate protection component of the presentinvention. In FIG. 2, a separate protection component 10′ is providesankle protection. The separate protection component 10′ includes, inaddition to a first covering body 12 and a second covering body 14, ajoint component 16.

The joint component 16 is respectively disposed at the sliding surface1442 and the contact surface 1242, or at the sliding surface 1442, thecontact surface 1242 or the combination thereof. The joint component 16has the maximum static friction coefficient.

For example, the joint component 16 may be a plurality of matricmaterials (eg. devil felt). In the embodiment of such fabric materials,the surface of one of the fabric materials is covered with a ringstructure and the surface of another of the fabric materials is coveredwith a hood structure. By means of the ring structure combining with thehood structure, a status of temporary tightening can be formed betweenthe sliding surface 1442 and the contact surface 1242.

For example, the joint component 16 may be of a pair structure such asrib and groove. In the embodiment of such pair structure, by means ofthe rib combining with groove, a status of temporary tightening can beformed between the sliding surface 1442 and the contact surface 1242.

The aforesaid fabric materials and pair structure shall both maintainthe second covering body 14 in the first covering body 12 before anexternal force F is exerted between the sliding surface 1442 and thecontact surface 1242; moreover, as an external force F is exertedbetween the sliding surface 1442 and the contact surface 1242, thecontact area between the contact surface 1242 and the sliding surface1442 is changed from a first contact area to a second contact area,thereby separating the second covering body 14 from the first coveringbody 12, as shown in FIG. 3.
